Order-disorder evolution in solid solutions of the NLO material KTiOPO4: Ko.88Rbo.12TiOPO4 and K0.465Rb0.535TiOPO4 in the temperature range 293-973 K

We determine the effect of radiation on the forced convection flow of an optically dense incompressible fluid along a heated horizontal stretching surface. The boundary-layer equations are transformed to ordinary differential equations containing a radiation parameter R*, velocity exponent parameter M, Prandtl number Pr, and surface temperature parameter teta. The effect of these parameters are studied. Graphical results for the velocity and temperature Aare presented and discussed.
